Convert kilojoule/hour to joule/second
Please provide values below to convert kilojoule/hour [kJ/h] to joule/second [J/s], or Convert joule/second to kilojoule/hour.
1 kJ/h = 0.277777778 J/s. To convert kilojoule/hour to joule/second, multiply the value by 0.277777778; to go the other way, divide by it (1 J/s = 3.59999999712 kJ/h). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Kilojoule/hour
A kilojoule per hour (kJ/h) is a unit of power representing the amount of energy in kilojoules transferred or converted per hour.
History/Origin
The kilojoule per hour has been used as a measure of power in contexts where energy transfer rates are expressed over time, particularly in engineering and scientific applications, though it is less common than standard SI units like watts.
Current Use
kJ/h is used in specific fields such as thermodynamics and energy management to quantify energy transfer rates, especially in systems where energy is measured in kilojoules and the rate is expressed per hour, though it is often converted to watts for standardization.
Joule/second
The joule per second (J/s) is a unit of power representing the rate at which energy is transferred or converted, equivalent to one watt.
History/Origin
The joule per second has been used as a measure of power since the adoption of the SI system, where the watt (W) became the standard unit of power, with 1 J/s = 1 W.
Current Use
J/s is primarily used in scientific and engineering contexts to quantify power, especially in physics and electrical engineering, often interchangeably with watts.
